One of the wettest Royal Adelaide Shows in recent years is drawing to a close and 891 ABC Adelaide's final show broadcast featured 891 Mornings with Matthew Abraham and David Bevan.

Matt and Dave kicked off the week of radio broadcasts on the opening day of the 2010 show.

Since then all 891 programs have broadcast from the Wayville Showgrounds.

The weather on the final Friday was a huge improvement on the first day although crowds were slow to build early.

Matt and Dave, as always, kept the assembled crowd entertained throughout the morning and took on the challenge of baking and decorating a cake.

However, something went terribly wrong in the baking process when the vanilla mixture emerged from the oven as a chocolate cake!

The morning duo were able to enlist the support of the President of the Cake Decorators Association of SA, Pam Lane, who transformed the cake into a work of art.

During the morning 891 Weekends presenter Ashley Walsh was sent to different parts of sideshow alley for a series of challenges set by the morning team.

The first involved Adelaide Lightning players Angela Marino and Augustina Zygaite trying their hand at the basketball shooting sideshow.

Even their combined experience was no match for the sideshow game with Angela scoring two goals from five shots while Augustina was unable to score from her five attempts.

Next up was a meeting of Gillard and Abbott, not the Prime Minister and Opposition Leader but Ainsley Gillard and Sam Abbott who agreed to see if the laughing clowns would have produced a more expedient election outcome.

Their scores would have seen a reversal of the election result with Sam Abbott scoring 18 and Ainsley Gillard 12 - at least it only took a few minutes to get a decision and not 17 days!

South Australian jockeys Clare Lindop and Simon Price also got into the spirit of the show agreeing to race each other in the Arabian Derby.

The game is played by rolling balls into holes, which in turn determine the speed of your camel.

In the end it was Simon who was victorious over Clare by the slimmest of margins.

Matt and Dave wrapped up their show broadcast with their regular Friday Fisho Greg James.
